Mechanical Engineer, PCBA Test Infrastructure, Robotics

About the Team

Our Robotics team is focused on unlocking general-purpose robotics and pushing towards AGI-level intelligence in dynamic real-world settings. Working across the entire model stack we integrate cutting-edge hardware and software to explore a broad range of robotic form factors. We strive to seamlessly blend high-level AI capabilities with the constraints of physical systems to improve peoples lives.

About the Role

We are seeking a Mechanical Engineer for a senior individual-contributor role leading printed circuit board assembly (PCBA) test fixtures and infrastructure for advanced robotic systems. You will independently turn evolving requirements into working fixtures make technical tradeoffs and own delivery from concept and detailed design through fabrication validation deployment and reliable operation.

This role combines development-lab work with deployment at contract manufacturers. You will build precision mechanical systems for board programming functional test and characterization including board nests probe plates connector interfaces alignment features clamps enclosures and thermal interfaces. You will partner with electrical firmware software manufacturing and reliability teams to make fixtures repeatable protective of delicate assemblies and maintainable as board designs evolve.

This role is based in San Francisco CA and requires in-person presence 4 days a week. Travel to contract-manufacturer sites is part of the role with timing based on build and deployment needs.

In this role you will:

• Own the mechanical architecture of PCBA test stations including frames board nests datum schemes access guarding ergonomics and serviceability.

• Design probe and bed-of-nails fixtures connector-mating mechanisms board supports clamps and interchangeable tooling for programming functional test and characterization.

• Use first-principles analysis and simulation to assess stiffness probe and insertion forces board deflection tolerance stacks thermal growth and fixture life; validate key predictions on hardware.

• Develop locating and compliance features that accommodate board and assembly variation protect components and solder joints and preserve contact repeatability across loading cycles and board revisions.

• Partner with electrical engineers on test-point access probe selection connector engagement ESD provisions cable routing cooling and interlocks; define motion and sequencing constraints with software and controls partners.

• Build assemble instrument and debug fixtures in the lab. Establish acceptance checks for alignment force board strain where needed contact repeatability and cycle life; separate fixture problems from board failures.

• Design safe loading pinch-point protection hard stops and operator access for manual or actuated fixtures. Make wear components easy to inspect clean and replace.

• Manage fabrication partners and component vendors. Release CAD drawings bills of materials tolerance analyses assembly instructions inspection plans and maintenance procedures.

• Own fixture deployment and acceptance at contract manufacturers including assembly and alignment checks correlation with lab fixtures operator training and troubleshooting. Support replication board-revision changes and maintenance through released documentation.

You might thrive in this role if you:

• Have strong mechanical intuition for precision interfaces load paths compliance tolerances and the behavior of delicate electronic assemblies.

• Move readily between analysis CAD vendor collaboration and hands-on assembly and debugging.

• Care about repeatable contact controlled forces operator usability and equipment that others can maintain.

• Take ownership from concept through reliable daily operation adapting fixtures to evolving boards and communicating clearly across electrical software manufacturing and operations teams.

Required qualifications

• Demonstrated ability to independently deliver significant precision-fixture or equipment projects from ambiguous requirements through detailed design fabrication validation and sustained use.

• Strong 3D CAD and released-drawing capability including complete fabrication and assembly packages bills of materials and revision control.

• Strong fundamentals in GD&T tolerance analysis locating schemes stiffness compliance contact forces and load paths.

• Hands-on ability to work with fabrication partners assemble and measure fixtures diagnose failures and iterate hardware in a lab or manufacturing environment.

• Ability to define and execute fixture acceptance checks for alignment force repeatability wear and safe operation using evidence to distinguish fixture problems from product variation.

• Ability to communicate interfaces and tradeoffs across electrical software manufacturing and operations teams and support deployment and troubleshooting at contract manufacturers.

Preferred qualifications

• Degree in Mechanical Engineering Mechatronics Robotics or a related field or equivalent practical experience.

• Prior PCBA test-fixture experience with board nests probe or bed-of-nails fixtures connector mating and protection of delicate electronic assemblies.

• Experience with ESD-aware tooling thermal interfaces actuated fixtures interlocks or structural and thermal simulation.

• Experience with NX SolidWorks Creo or equivalent tools; robotics hardware; or fixture replication and new-product builds at contract manufacturers.

What success looks like

• Deliver a reusable PCBA fixture that meets agreed alignment contact board-support and loading requirements with demonstrated repeatability and protection of the assembly under test.

• Validate fixture wear and cycle life identify sources of intermittent contact or board loading and improve contact-related failures changeover time and serviceability against agreed targets.

• Deploy and accept the fixture at a contract manufacturer with released CAD drawings inspection checks assembly instructions spare-parts information and maintenance procedures that enable others to reproduce and sustain it.
